Buy a Barventure map book for $20 and get BOGO drink deals (including mugs of beer and glasses of wine) at scores of bars in neighborhoods all over Denver. Super-premium drinks are excluded, and as the publisher notes, “A drink means a drink . . . not a bottle of wine, bottle of whiskey or a pitcher/growler of beer.” Each bar stamps its spot in your map book to confirm that you have used your Barventure there. The current BOGO offers are in effect through December 29. Click here to purchase.
